Early Warning Signals of Esophageal Cancer May Be Hiding in Plain Sight

A Nature Medicine study suggests esophageal adenocarcinoma appears to begin from Barrett’s esophagus in every case.

Even when precancerous tissue is no longer visible, tumor and genomic data still point to that origin.

Biomarker signals such as TFF3 and REG4 could help identify risk earlier and support better screening.

The findings strengthen the case for using Barrett’s esophagus markers to detect esophageal cancer before it advances.
